Earlier today, we brought you news on the European and Japanese specification versions of the refreshed 2012 GT-R, and now it's time for the skinny on the North American variant that will go on sale on January next year as a 2013 model year car.
The refinements for the updated N.A. GT-R are more or less the same with its Euro counterpart and are highlighted by the changes to the 3.8-liter bi-turbo V6 that include improved intake efficiency, reduced airflow resistance through an enlarged air intake duct for the intercooler, and improved exhaust emissions efficiency.
As a result, the 2013MY GT-R is rated at 545-horses and 463 lb-ft, an increase of 15HP and 15 lb-ft over the outgoing model.
Additionally, Nissan engineers have refined the transmission and retuned the suspension, while a handmade dry carbon rear spoiler has been added to the GT-R Black Edition model.
Other changes include the addition of a new blue lighting treatment inside the tachometer ring, while a RearView Monitor, Nissan Navigation System with XM NavTraffic with Real-Time Traffic Information and NavWeather capabilities, and Bluetooth Hands-free Phone System, are now standard on both the GT-R Premium and the GT-R Black Edition models.
Unfortunately, the U.S. won’t be getting the lighter and more hardcore GT-R Track edition.
